.WHEEL-PLOW.

SPECIFICATION forming part of Letters PatentI No. 393,707. dated November 27, 1888.

Application filed October 1888. Serial No. 286.833. (No model.)

To @ZZ whom, it may concern.-

Beit known that I, SIMON A. KERNS, re' siding at Rock Island, in the county of Rock Island and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Wheel-PloWs, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure l is a perspective showing a portion of a bent axle and a plow-beam and the devices for raising and lowering or leveling the plow. Fig. 2-isadetail, being asection through the parts thereby shown. Fig. 3 is a detail, being a side view ofthe main lever, two of the racks, and the locking devices which engage with such two racks.

The object of this invention is to provide a wheel-plow with improved devices for raising or lowering and leveling` the plow, which I accomplish as illustrated in the drawings and as hereinafter described.

That which I claim as new will be pointed out in the claim.

In the drawings, A represents one part of the bent axle. The outer end of this part A is not shown in the drawings, but is adapted to receive a wheel, as usual.

B is a sleeve upon and secured to the part A of the axle, so that this sleeve B revolves a is an arm which extends out from the sleeve B, and the outer end of this arm a is enlarged and provided with a rack, O, and a slot, c.

D represents the other part of the bent axle, which, as shown, consists of three parts, d ef, d being a sleeve located loosely upon the outer end of the sleeve B, e being an arm connected with the sleeve d, andf being a piece of metal bolted, as shown, to the part e, the outer end of which is adapted to receive a Wheel.

` E is a plow-beam-connected with the axle in any suitable known manner;

F is a rack secured to the plow-beam.

G is the main lever placed loosely on the sleeve B.

H is a rack secured to the main lever G.

I is a second lever, which is located loosely upon the sleeve B.

g is an ear projecting out from a plate, h, which is bolted to the lever I. iis another ear, which is secured to the parte. (See Fig. 2.)

J is a coiled spring located between the two ears g and i and held in place by a bolt, j, which passes through the ears and the spring, and is held by a nut on its lower end, by means of which nut the tension of the spring J can be adj usted.

7c is a springbolt which engages with the rack O. This bolt is operated by means of a thumb-piece, l, secured to the main lever G, the thumb-piece and bolt being connected by means of a rod, m. a is another spring-bolt arranged to engage with the rack F, and it is operated by means of a thumbpiece, o, upon the lever G, which thumb-piece is connected with the bolt by means of a rod, p. q is another spring-bolt arranged to engage with the rack H. It is operated by means of a thumb-piece attached to the lever l, this thu nib-piece being connected with the lock-bolt q by means of a rod, r. Y

sis a bolt, which can be inserted into the sleeve B before it is placed upon the axle A.

t is a washer.

The sleeve B, with its arm c and rack C, may be cast together. The sleeve d and arm e may be cast together. The levers G and I are, as shown, made of two parts bolted together.

The operation is as follows: I/Vhen the three springbolts k, n, and q are all engaged with 'their respective racks, the axle and plow will be held in whatever position they may then occupy. lf the bolt n be released from the rack the other bolts remaining engaged with their respective racks', the position of the whole axle can be changed by the movement of thelever G up or down, thus raising or lowering the plow. If the bolts it and lc be both released, the other bolt remaining engaged with its rack H, the main lever G can be moved up or down,` and thus the position of the part D ofthe axle can be changed,which will change the positiojn of the plow. It the bolts a and q be both released, the bolt k remaining engaged with its racl; O, the movement of the lever G will change the position of that part of the IOO axle marked A, which will raise or lower the plow. If the bolt q only be released, the other two remaining engaged with their racks, then bythe movement of the lever I the position of 5 that part of the axle marked D can be changed for the purpose olleveling or guiding the plow. The movement of the lever I acts upon the part D ofthe axle through the spring J. The spring J allows the wheel carried by the part 10 D of the axle to pass over ordinary inequalities without changing t-he position ofthe plow. The devices herein shown and described are in some respects similar to devices for a like purpose shown in a pending application of my I 5 own; but by means of the devices herein shown and described for raising and lowering or levcling the plow the action is more positive, and the operator can force the axle into any de sired position, whether the plow is standing 2o still or be in motion, much more readily than with the devices shown in my said pending applieation.

"What I claim as new, and desire to secure by Letters Patent, is as follows:

In a wheel-plow, a divided and bent axle, 25 in combination with a plow-beam carrying a rack, F, a sleeve, B, secured to one part, A, of the axle and carrying a rack, C, a sleeve, d, connected with the other part ofthe axle and placed loosely on the sleeve B, a main lever, G', a rack, lI, supported by the level` (l, a lever, I, both levers being placed loosely on the sleeve B, bolts arranged to engage with the racks C, F, and H, and a spring, J. substanA tially as and for the purposes specilied.
